<p>PROBLEM TO BE SOLVED: To develop a new drive mechanism for elements around an output shaft, for solving an issue that a large-sized engine needs to be installed in a space conventionally used for installing a small-sized engine.SOLUTION: A drive mechanism for a pavement material cutting device 1 of the present invention is for a device that forms a continuous cutting groove Ps on a paved surface P as it moves on the paved surface P while operating a rotary cutter blade 30. The device has a crank of an engine 4 laid horizontally on a main body 10 in the direction orthogonal to the shifting direction of the device, has an end of an output shaft 42 supported on the side with a flywheel 401 of the engine 4, while the other end of the output shaft 42, which is a free end, is supported by a support bracket 44 that is fixed with respect to an engine block 402 of the engine 4, and the output shaft 42 has an output pulley 43 installed between the inner side of the support bracket 44 and the flywheel 401.</p> |
